Letters Patent No. 101,387, dated March. 29, 1870.

The Schedule referred to in these Letters-Patent and making part of the same To all whom it may concern Beit known that I, SEVERIN SIEBOLD, of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Lining Terrets; and I do hereby declare the following to be a clear and exact description of the same, suilicient to enable others skilledin the art to which the invention appertains to fully understand and use the same, reference being had to the accompanying drawings which are made' a part of this specification, and the several ligures of which will be particularly mentioned in explanation of the consecutive steps or stages of the process under which the invention is carried out.

It is customary to line the interior of iron terret rings with another or diierent Vkind of metal, which is swaged to the ling so as to form a firmly united continuous sheathing for theinternal surface. Hitherto a lining strip of proper length having been obtained, the ends of the strip were joined by brazing, and the flat ring, fig. 1, so formed, was applied or united to the terret by swaging, as aforesaid. The separation ofthe ends of the brazed lining ring, either during the act of swaging the same or subsequently in using the article, has been of frequent occurence, and it is the especial object of my invention to so secure the ends of the lining strip that they shall, during the process of applying the lining or alter the lining has been applied, be capable of withstanding any force having atendencyto separate them or disturb their proper relative positions.

To this end I provide the inside of the terret ring with a slit or fissure, as shown at a, Figures 2 and 4, wherein are inserted and tightly held the ends of the lining stripb.

In lining the ling according to my improved plan the strip is introduced, as seen in Figure 3, then the ,hook aud-the other at ornear -been completed the joint or junction of the ends of the strip is scarcely, if at all, perceptible. A separate slit or fissure may be employed to receive 'each end of' the lining strip. The twosuch slits should be so near together as to enable the finishing to be `done as though only one slit were made use of.

These are obvious reasons pointing to the superiority of a terret lined according to my invention. The invention greatly cheapens and simpliles the manufacture.

Harness check-hooks may also be -lined in the same manner by cutting or forming two slots therein, one of which shall be at or near the upper termination of the the lower termination thereof, 'and then lining the hook in a manner similar to that of the terret. Y

Having thus described my invention,

What I clziiin as new, and desire to secure by Letters Patent, is-

A terret having the ends of' its lining secured by means of a fissure or narrow opening in the terret ring, substantially as and for the purpose herein set forth.

The above signed by me this 23d day of February, 1870.
